Has anybody had a problem with the side tone on the SV8100. I have had some SV8100 install's where the side tone has static as you talk while on a C.O. call. Internal is fine but when you talk on a outside line as you talk you hear static. The lines are a little hot but well within spec. It just suck's that the customer say's that they never have had a problem with the "old" system.

Have an SV8100 doing the same thing. Didn't start until system had been installed for about a month. Have checked all my CO's for any type of trouble and none found. Have referred it to our vendor, who has referred to NEC. Heard nothing from NEC yet.

Are you using IP fones on these sites.?? Have had issues here with them but not the DT300 TDM series..

I have 4-12 Button DT-330 phones, 4-port Inmail, 3-C.O. lines. No VOIP.

Check CO line grounding.

Has anybody come up with a solution. It seems to be happening with Time Warner. I can make it go away with Line Attenuators I bought from Sandman but was wondering if there is something in programming I can do.

Thanks

As it seems to go away with attenuators try changing the trunk trans levels in PRG14.01.02/03 and see if that helps..
